WOVEN PILE FABRIC.

SPECIFICATION forming part of Letters Patent No. 484,606, dated October18, 1892.

Application filed March 31, 1891.

To all whom it may concern-.-

Be it known that I, FRED PEARSON, a citizen of the United States,residing in the city and county of Philadelphia, in the State of Penn-.

sylvania, have invented certain new and useful Improvements in \VovenPile Fabrics, of which the following is a specification.

My invention relates to the class of fabrics in which ground orfoundation webs are formed independently of each other but are united bycommon pile threads passing from one tothe other.

It is the object of my invention to produce a novel compound fabriccomposed of three independent Webs formed of ground Warp and weftthreads, united by pile threads, and adapted to be separated to formthree distinct merchantable fabrics.

The double pile fabrics heretofore constructed have consisted of twofoundation or ground webs, united by pile threads engaged with the weftthreads of each and passing and repassing from one to the other. In myimproved treble fabric I construct two exterior webs of material, andengage pile warp threads with each, but instead of passing said pileWarp threads from one exterior fabric to the other, I pass each from itsrespective exterior web to an interior or central web and I then returnit to said exterior web. By reason of this arrangement the two exteriorwebs, after the fabric is divided, are similar in that each has oneplain face and one pile face, while the central fabric has two pilefaces.

In the drawings, Figure 1 is a longitudinal sectional elevation of afabric embodying my invention. Fig. 2 is a diagrammatic plan on line ma: of Fig. l, sight being taken toward the central fabric, the diagrambeing designed to illustrate the arrangement of the threads.

Similar letters of reference indicate corresponding parts.

In the drawings, a a a a a are the weft threads of the upper fabric, b bb h b b the weft threads of the lower fabric, and c c c c c the weftthreads of the central or intermediate fabric.

Serial No. 387,115. (No model.)

d d are a pair of ground warp threads of the upper fabric. These groundwarp threads are interwoven in any usual manner with the weft threads ofsaid fabric, but are preferably, as shown, crossed after every secondweft thread.

6 e are the ground warp threads of the lower fabric, and are preferablyarranged in the same manner as the ground warp threads of the upperfabric.

ff are the ground warp threads of the central fabric, and are preferablyin their interweaving with the weft threads thereof crossed after eachof said threads.

G G are pile warp threads common to the upper fabric and the centralfabric. These threads may be interwoven with the upper fabric in anydesired manner varying with the character of the fabric to be produced.I prefer however to interweave them in the manner illustrated, that isto say to laterally separate and not to cross them, and to engage thethread G with the weft threads 'of the upper and intermediate fabrics bypassing it over the weft thread a, under the weft threads a and a andover the weft thread 0. of the upper fabric, to carry it to the centralfabric and around the weft thread 0 thereof, to then carry it back toand over the weft (1 under Wefts a and 0 over weft a and to then carryit to the central fabric, and around the weft 0 to return it to theupper fabric, and so on. The thread G is thus engaged with every fourthweft thread of the central fabric, and the loops or bights of saidthread descend to and make engagement with the wefts of the centralfabric between the two threads of every alternate pair of weft threadsof the upper fabric. The adjoining pile thread G is interwoven with theupperand central fabrics in a similar manner, except that said thread Gengages with other threads of the central weft, and the loops or bightsof said thread G which descend to make engagement with the wefts of thecentral fabric, pass, in descending, between the other pairs of weftthreads of the upper fabric.

H H are the pile warp threads common to the lower and central fabrics,and these threads preferably follow the arrangement of the threads G G'Xdescribed, being each similarly engaged with four weft threads of theexterior fabric, then with a central weft thread and then with four moreweft threads of the exterior fabric, and so on. The two lower pilethreads H H shown, engage with the central weft threads not engaged bythe pile threads G G", so that all the central weft threads willthroughout the breadth of the fabric be engaged by a like number ofloops of pile. V

The fabric is to be divided between the upper and central and lower andcentral webs respectively. The upper and lower webs will presentsurfaces of uniform unridged pile, while the central web will have pileon both faces.

Having thus described my invention, I claim and desire to secure byLetters Patent:

1. As an article of manufacture, a blank adapted to be split or cut toform three pile fabrics, said blank consisting of three ground webs, anupper, a central, and a lower, the upper and central webs being unitedby a set of pile warp threads common to both, and the lower and centralwebs being united by an independent set of pile warp threads common toboth, substantially as set forth.

2. As an article of manufacture, a blank adapted to be split or cut toform three pile fabrics, said blank consisting of three independentground webs, two exterior and one central, one exterior web and thecentral web being united by a set of pile warp threads common to both,which pile warp threads are each caught in the central web by singlepicks of weft therein, the other exterior web and the central web beingunited by an independent set of pile warp threads common to both,substantially as set forth.

3. As an article of manufacture, a blank adapted to be cut or split toform three pile fabrics, said blank consisting of three independentground webs, two exterior and one central, one exterior web and thecentral web being united by a set of pile warp threads common to both,which pile warp threads are each caught in the central web by singlepicks of weft therein, and in the exterior web by a plurality of picksof weft therein, the other exterior web and the central web being unitedby an independent set of pile warp threads, substantially as set forth.

4. As an article of manufacture, a blank adapted to be split or cut toform three pile fabrics, said blank consisting of three independentground webs, two exterior and one central, one exterior and the centralweb being united by a set of pile warp. threads, and the other exteriorweb and the central web being united by an independent set of pile warpthreads, all the pile warp threads being caught in the central web bysingle picks of weft therein and each caught in an exterior web by aplurality of picks of weft therein, substantially as set forth.

5. As an article of manufacture, a blank adapted to be split or cut toform three pile fabrics, said blank consisting of three independentground webs, two exterior and one central, one exterior web and thecentral web being united by a set of pile warp threads common to both,which pile warp threads each in going from the exterior web to andreturning from the central web, pass between the same' pair of weftthreads of said exterior web, the other exterior web and the central webbeing united by an independent set of pile warp threads, substantiallyas set forth.

6. As an article of manufacture, a blank adapted to be split or cut toform three pile fabrics, said blank consisting of three independentground webs, two exterior and one central, one exterior web and thecentral web being united by a set of pile warp threads common to both,and the other exterior web and the central web being united by anindependent set of pile warp threads common to both, the pile warpthreads each, in going from their respective exterior webs to andreturning from the central web, passing between the same pair of weftthreads of the exterior webs, substantially as set forth.

7. As an article of manufacture, a. blank adapted to be cut or split toform three pile fabrics, said blank consisting of three independentground webs, two exterior and one central, one exterior web and thecentral web being united by a set of pile warp threads common to both,each pilev thread being in the central web engaged with a pick of Weftintermediate between the picks of weft with which the next adjacent pilethreads of the (same set are engaged, the other exterior web and thecentral web being united by an independent set of pile warp threads,substantially as set forth.

8. As an article of manufacture, a blank adapted to be cut or split toform three pile fabrics, said blank consisting of three independentground webs, two exterior and one central, one exterior web and thecentral web being united by a set of pile warp threads.

and the other exterior web and the central web being united by anindependent set of pile warp threads, each pile warp thread being in thecentral web engaged with a pick of weft intermediate between the picksof weft with which the adjoining pile threads of the same set areengaged, substantially as set forth.

9.. As an article of manufacture, a blank adapted to be cut or split toform three pile fabrics, said blank consisting of three independentground webs, two exterior and one central, each consisting of groundwarp threads and ground weft threads, the ground warp threads being inthe exterior webs crossed after every second pick of weft, and

I in the central Web crossed after each pick of weft, the upper andcentral webs being united by a set of pile Warp threads common to both,and the lower and central webs being united by an independent set ofpile warp threads common to both, substantially as set forth.

In testimony that I claim the foregoing as my invention, I have hereuntosigned my 10 name this 11th day of December, A. D. 1890.
